Aalborg 3-Pasos
Aalborg 3-Pass is an oil and gas-fired industrial boiler, which is designed and optimised with the total of Alfa Laval's technical and innovative competencies in every detail - inside out.
A thoroughly industrial design based on recognised and well proven principles. Utilising the latest technology, the boiler is optimised to assure quality, reliability, long life, easy maintenance and sound economy.
Customer benefits
Easy installation
The boiler is ready to be plugged in. Supplied with ready-mounted burner, control panel, fittings and cables.
Compact design
The small foot-print makes the boiler easy to incorporate.
Easy inspection and maintenance
To the greatest possible extent, all connections and valves are located on top of the boiler - easily accessible during installation, inspection and maintenance. A number of manholes facilitate internal inspection.
Easy to clean
The smoke tubes are fast and easy to clean thanks to the low number and efficiency of the spiral tubes.
Uniform, high steam quality
The boiler’s efficient steam drier delivers a dry, saturated steam. A superheater can also be installed.
Improved combustion
The furnace has a comparatively low heat release ratio and provides ample space for the flame. This improves combustion and limits flue gas emissions.
Accessories
The boiler plant can be equipped with economiser, superheater, condensate tank, deaerator, feed water tank, blow down tank, and O2 combustion control.

Cómo funciona
Partes
Las superficies que transfieren el calor se ubican de forma simétrica al horno en el centro de la caldera para garantizar una circulación óptima del agua. El horno está diseñado con una superficie plana para bajas presiones y con una superficie corrugada para altas presiones y mayores capacidades. La cámara de reversión es enfriada en su totalidad por medio de agua para reducir la refracción a lo mínimo y todas las partes de la caldera son fabricadas con materiales cuidadosamente seleccionados y que no contengan acero de alta resistencia.Sistema de Control
- Sistema de administración del quemador que permite controlar carga y secuencia
- Sistema de control de niveles de agua y equipo de seguridad
- Arrancadores de motor y calentador de aceite
